A glucose in urine test measures the amount of glucose in your urine. Glucose is a type of sugar. It is your body's main source of energy. A hormone called insulin helps move glucose from your bloodstream into your cells. If too much glucose gets into the blood, the extra glucose will be eliminated through your urine. A urine glucose test can be used to help determine if blood glucose levels are too high, which may be a sign of diabetes.
Other names: urine sugar test; urine glucose test; glycosuria test
What is it used for?
A glucose in urine test may be part of a urinalysis, a test that measures different cells, chemicals, and other substances in your urine. Urinalysis is often included as part of a routine exam. A glucose in urine test may also be used to screen for diabetes. However, a urine glucose test is not as accurate as a blood glucose test. It may be ordered if blood glucose testing is difficult or not possible. Some people can't get blood drawn because their veins are too small or too scarred from repeated punctures. Other people avoid blood tests due to extreme anxiety or fear of needles.
Why do I need a glucose in urine test?
You may get a glucose in urine test as part of your regular checkup or if you have symptoms of diabetes and cannot take a blood glucose test.
Symptoms of diabetes include:
More frequent urination
What do the results mean?
Glucose is not normally found in urine. If results show glucose, it may be a sign of:
Pregnancy. As many half of all pregnant women have some glucose in their urine during pregnancy. Too much glucose may indicate gestational diabetes.
A urine glucose test is only a screening test. If glucose is found in your urine, your provider will order a blood glucose test to help make a diagnosis.
